Title: Picture signal transmission system
Inventor: ASHIBE MINORU
IPC: H04N7/01
Filed: 1991-08-29
Abstract: PURPOSE:To reduce a difference of noise quantity for each picture element caused attended with matrix transformation at the time of transmission of a picture signal. CONSTITUTION:A transformation circuit 1 at a sender side applies matrix operation to a picture signal 50 by using plural picture elements as one set and transforms the signal into a main signal 51 and an auxiliary signal 52 and they are sent to a receiver. An inverse transformation circuit 2 of the receiver applies the operation inverse to the matrix implemented by the transformation circuit 1 to decode a picture signal 53. The matrix elements used to generate the auxiliary signal 52 on the sender side is selected by minimizing the difference from noise quantity for each picture element of the decoded picture signal 53.

Title: Thermal head
Inventor: SHIRAISHI MIKIO
IPC: B41J2/335
Filed: 1986-09-19
Abstract: PURPOSE:To prevent dimensional fluctuation of a pixle, by forming a heating element on the surface of a thin insulating resilient member and constructing a thermal head such that a supporting member for said resilient member and the heating element are thermally insulated, thereby reducing production of available energy and making the dimension at the heating section constant. CONSTITUTION:A heating element 4 is sufficiently thin when compared with a supporting film 6, where the heating element 4 is composed of electrically resistant material and provided with a protection film 11 for protecting the heating element 4 from oxidation upon heating. Under the condition where the supporting film 6 deforms resiliently along the curvature of an intermediate recording medium 2 which is pressed against the surface of the protection film 11, the protection film 11 and the intermediate recording medium 2 are contacting tightly thereby thermal loss is scarcely, produced. The thickness and the specific heat of the recording medium 1 and the intermediate recording medium 2 is approximately the same as those of the supporting film 6, and when the heating element 6 is heated, approximately 90% of the produced heat is transmitted to the intermediate recording medium 2 and the recording medium 1. In other word, the thermal resistance between the heating element 4 and the recording medium 1 or the intermediate recording medium 2 is far smaller than that between the heating element 4 and a frame 7 during usage, thereby the intermediate recording medium 2 and the recording medium 1 can be heated efficiently.

Title: Method for detecting body without contacting
Inventor: MATSUI IZUMI
IPC: G01B11/245
Filed: 1984-10-21
Abstract: PURPOSE:To perform three-dimensional detection with a small number of light sources by converting the direction of luminous flux from an oscillator to between two photodetecting elements through a luminous flux converting means, and forming a desired plane or three-dimensional string spread type light track. CONSTITUTION:The laser luminous flux 20 from the laser oscillator 1 is direction-converted by a reflecting mirror 2 into luminous flux 21, which is reflected by a reflecting mirror 3 to obtain luminous flux 22. The luminous flux 22 passes through an optical fiber 5 from a ferrule 4 and is projected from a ferrule 6 as luminous flux 23, which is then passed through an optical fiber 9 similarly and projected as luminous flux 24. Part of this luminous flux 24 is diffused spectrally by a reflecting mirror 10 and travels straight as luminous flux 27, which reaches a photodetecting element 11 and is reflected to obtain luminous flux 25; and the luminous flux is reflected by a reflecting mirror 12 to obtain luminous flux 26, which reaches a photodetecting element 13. Thus, the luminous flux 20 emitted by the one laser oscillator 1 is made into the string spread type light path (flux) to perform three-dimensional detection.
